On my -CURRENT machine, FreeBSD jehovah 5.0-CURRENT FreeBSD 5.0-CURRENT #0: Sat May 13 15:11:13 EDT 2000 root@jehovah:/usr/src/sys/compile/JEHOVAH i386 (obviously a little out-dated), I have recently noticed unusual problems with the linux module which, by the way, is of the same date. The first problem I discovered first came up while building the StarOffice5 port. After checking the dependency for linux's libc5, it _spontaneously_ reboots. No panic(), hence no debugger. I've never seen this sort of behavior before and have no idea what could have caused it. However, I noticed a related incident, which I can reproduce. What I did was, for kicks, kldunload linux, and then make install the staroffice5 port, and this time, I got a page fault and panic() from within malloc, which was trying to move something located at an address on an unmapped page to a register. I can reproduce this easily at the moment, with the following: #!/bin/sh while true; do kldload linux; kldunload linux; done A quick kldunload linux followed by a quick kldload linux does it on the first iteration. What's more odd is that now, after panic()ing the machine a couple of times with the above, I can reproduce the spontaneous reboot easily too, by just starting up linux Netscape! At the moment, I cvsup-ed new sources, and am rebuilding world and a fresh new kernel, at which point I'll try to reproduce this again. I remember seeing this in earlier -CURRENT, too, just never got around to playing with it.
